Referring now to the drawings in detail, reference is first made to FIGS. 1 and 2 wherein there is illustrated the overall exterior of the book which is the subject of this invention, the book being generally identified by the numeral 20. The book 20 has the general appearance of a conventional book and includes a housing 22 of a configuration to resemble the pages of a conventional book. The housing 22 includes a base 24 in the form of a book recover page. The housing 22 also includes a left side 26 in the form of the backing or binder of a book page. The main portion of the housing 22 is configurated to resemble pages of a book and includes a top panel 28. The top panel 28 is provided with a displaceable panel portion 30 which is hingedly connected to the top panel 28 by way of a hinge 32.

The displaceable panel 30 is provided with an opening in which is positioned a magnifying lens 34. Further, the displaceable panel 30 is provided with a release button or knob 36 which facilitates the lifting of the panel 30.

The book also includes a cover in the form of a book front cover 38 which is connected to the backing 26 by way of a hinge 40 which permits the book to be "opened" or "closed" with the front cover 38 protecting the lens 34 in the "closed" condition of the hook.

It is also to be understood that the portion of the housing 22 which has the appearance of pages of a book will have end walls 42 and 44 and a side wall 46, the side wall 46 being disposed remote from the back 26.

With reference to FIGS. 3 and 4, it will be seen that there is mounted within the housing 22 at the corner between the walls 42, 46 a drive motor 48. In the illustrated embodiment of the invention, the motor 48 is mounted on a support 50 which is slideable in a direction parallel to the axis of the motor and slides 52. The motor 48 has a drive shaft 54 which is provided with a sleeve type coupling 56 for engagement over and within a notch in the end of a shaft, such as shaft 58.

The motor 48 is provided with a control knob 60 which, when rotated, will control the direction of rotation of the motor 48 and where moved axially will shift the motor parallel to his axis so as to shift the coupling sleeve 56.

In alignment with the shaft 54 of the motor there is a pair of cradles 62 into which a shaft, such as the shaft 58 may be resiliently snapped with the cradle 62 mounting the shaft 58 for rotation. When the motor 48 is in this left hand position, the coupling sleeve 56 will engage over the end of the shaft 58 and connect the shaft 58 to the motor shaft 54 for rotation therewith.

At the opposite corner of the housing 22 at the intersection between the walls 44, 46, there is mounted a mounting sleeve 64 on a slide plate 66 with the plate 66 having its opposite ends mounted within slides 68. A shaft 70 is rotatably journalled in the mounting sleeve 64 and extends through the wall 46. That end of the shaft 70 which extends through the wall 46 is provided with a knob 72 which may be used either to rotate the shaft 70 or to axially position the shaft.

The opposite end of the shaft 70 is provided with a coupling sleeve 74 of the same type as the coupling sleeve 56. Axially aligned with the shaft 70 is a further shaft 76 which is interlocked with the shaft 70 by means of the coupling sleeve 74 when the mounting sleeve 64 is moved to its left hand position. The shaft 76 is resiliently snapped into and supported by cradles 78 which are identical to the cradles 62.

It will be seen that the coupling sleeves 56, 76 carry drive pulleys 80, 82 which are aligned and which have entrained thereover a drive element 84 which may be in the form of a very small diametered cord. Thus, the shaft 70 is rotated in unison with the motor shaft 54.

In the simplest form of the invention, the shaft 58 will be provided with a spool 86 on which an opaque web 88 is normally stored and which web 88 has printed text thereon with the text being miniaturized. There will be associated with the spool 86 a take-up spool 90.

Referring now to FIG. 5, it will be seen that the panel 30 carries on opposite sides of the magnifying lens 34 elongated shoes 92 which extend in the length direction of the web 88. The shoes 92 may be spring mounted by way of mounting rods 94 which are engaged in mounting the sleeves 96 with the rods 94 being in projecting relation due to the action of springs 98.

When the panel 30 is closed, the shoes 92 engage the web 88 and hold it parallel to the rear cover 24 in spaced relation to the magnifying lens 34 at a preselected distance.

It is to be understood that the motor 48 will normally be powered by a battery 100. The battery 100 will be connected to a control switch 102 having a push button 104. When the button 104 is depressed, the motor 48 will be driven in the direction for which the control knob 60 is set. By selectively coupling the spools 86, 90 to their respective shafts, the spool 86 may initially function as a feed spool and the spool 90 functions as a take up spool. After the desired portion of the text carried by the web 88 has been read, the feed spool 86 may be driven to rewind a web on the spool 86.

It is to be understood that the power source for the motor 48 may either be a battery or a conventional AC supply. Accordingly, the backing or wall 26 may be provided with an adapter unit 106 which, as is best shown in FIG. 10, may include a receptacle 108 for a power cord, and an energy selector switch 110 which may either select AC current from the external power source or DC current from the battery 100.

Referring now to FIG. 4, it will be seen that in lieu of a direct drive between the motor and the shaft 58, there may be a gear drive with the motor shaft 54 carrying a drive gear 112 and the shaft 58 carrying a driven gear 114. Further, there may be additional gears in the gear train. Also, it is to be understood that the gear 114 may be separate from the shaft 58 and carry a coupling sleeve, such as the coupling sleeve 56. Finally, the gear 114 may be mounted for movement axially on the shaft 58 to selectively connect or disconnect the shaft 58 relative to the motor 48.

It is also to be noted that the motor shaft 54 still carries a drive wheel 80.

Preferably the web 88 is supplied in the form of a cassette. In FIG. 6 there is illustrated a preferred embodiment of a cassette 120 which includes two separate casings 122, 124 disposed in a posed relation. The casings 122, 124 may be identical and each includes a shaft 126 which projects through and is rotatably journalled in end walls 128 of the casings. Each of the casings is provided with a lower slot 130 through which the web 88 carried by a supply spool 132 may pass to a take-up spool 134.

Opposed walls of the cases 122, 124 will be provided with a combination of pins 136 and sleeves 138 for receiving the pins whereby during the storage of the web 88, the casings 122, 124 may be interlocked as shown in FIG. 6. However, these casing may be readily separated for the mounting of the shafts 126 within the cradles 62, 78 in the same manner as the spools 86, 90.

In FIG. 8 there is illustrated a further form of cassette generally identified by the numeral 140. The cassette 140 is in the form of a single one of the casings 122, 124, the casing being identified by the numeral 122. In this construction the web 88 is provided at the feed end thereof with a sleeve 142 which may be readily engaged over a separate shaft (not shown) for winding onto that shaft.

In FIG. 9 there is illustrated still another form of cassette, generally identified by the numeral 144. The cassette 144 includes two casings 146, 148 which are similar to the casings 122, 124 but which are integrally formed therewith an intermediate guide 150. The guide 150 is provided with a central opening 152 and has edge portions which receive and guide the edges of the web 88. The casings 146 are provided with shafts 154 which are similar to the shafts 126.

It is to be understood that when a cassette is utilized, there will be no need for the positioning shoes 92 of FIG. 5.

Although the book 20 is particularly adapted to be read in external light, the same way as any book, it is feasible in accordance with this invention to provide a light (not shown) within the housing 22 for illuminating that portion of the printed text which is in alignment with the magnifying lens 34. Further, it may be desirable to black-out the top and bottom parts of the lens area so as to see and read through the central area only or between two horizontal lines. The blacking out can be accomplished by removably placing a screen over the lens area to permit seeing and reading through the central area only. Alternatively, it may be desirable to have the top and bottom of the lens in a gray color. This will permit seeing through the entire lens area, but favor seeing through the central area. This can serve as a means for improving the reading rate of the reader. As will also be apparent, the size of the print on the printed web can be varied and mated with the strength of the magnifying lens in order that a greater or lesser number of pages can be contained in a suitably sized reel or printed web.

Although only several forms of book constructions and cassettes for the printed webs have been specifically illustrated and described herein, it is to be understood that minor modifications may be made in the book construction and the cassettes without departing from the spirit or scope of the invention as defined by the appended claims. For example, the web can include a sound track along the edge or edges thereof in order that at least a portion of the web produces sound. The sound track will preferably be synchronized with the web speed by use of a variable speed speech control. Webs having sound tracks of this type are known in the art.
